thats a good idea, too. thanks.

I have some thin plywood, will have to see just how thin tho...using glass as a print surface it kinda takes away from the space between the frame & the underside of the bed.

may end up using some thin guage sheet metal like wardjr - less bulk...

could always lay up some regular fiberglass using resin and cut that to fit... LOL

I have a thin piece of wood that I have been meaning to drill the holes out and put under my bed to hold the insulation up. It will also provide some additional insulation.

Thanks guys.

I've used Kapton to wrap the whole bed, and hold the insulation in place before I got rid of all of that and went with a PCB heater.

I have a thin piece of scrap sheet metal that I used to sandwich the heater and insulation in place.

this is on an SD4 - the fiberglass insulating mat on the underside of the heat bed has begun sagging, causing some issues with keeping consistant heat on the bed. I can use the putty knife/scraper to push it back up and it will stay for a little while (a couple of hours during printing) then start sagging again...

what can I do/use to stick it back on, or keep it in place better?

or is there a better alternative - short of replacing the bed?
